Sleeves of moomin emulsion

Description:	The magic of the moominhide sleeves can be attributed to harvesting the emulsion when the moomin is at a very young age. Once they pass into maturity, the moomin is strong enough magically to prevent the magic from staying within its skin when it dies. Each sleeve requires at least four young moomin to sacrifice their lives. They must be killed under a waxing crescent moon in the middle of winter by an evil priest with an unholy sacrificial dagger.
